Maraviroc is an antiretroviral medication that may help in improving mental function in HIV
infected patients with mental problems by decreasing inflammatory tendencies. We will test
this in a clinical trial of 42 HIV infected individuals with some mild to moderate mental
problems who are already on HIV medications and doing well. We will add Maraviroc or a sugar
pill to their HIV medications and see if mental function improves over 48 weeks. This study
will be conducted at 2 sites in Hawaii and Puerto Rico.
